PMN binding and spreading on Ab-coated targets.
(A) Numbers of Ntg Mac-1+/− PMNs (■), Tg Mac-1+/− PMNs (■), and Tg Mac-1−/− PMNs (░) bound to BsAb [A77 × 520C9]-opsonized SK-BR-3 cells were determined after 30 and 60 minutes. Results represent mean ± SEM from 3 individual experiments. (B) Tg Mac-1+/− PMNs (left) and Tg Mac-1−/− PMNs (right) were plated on IgA-coated glass slides for 30 minutes and stained for actin. Cell morphology was imaged in x/y and x/z directions (inserts), using confocal microscopy. Bars indicate 15 μm. Experiments were performed at least 4 times, yielding similar results.
